Body In Numbers

In the final episode of Body In Numbers we look at a whole sweep of our body’s journey through life, examining what our body gets up to, how it keeps going and what it’s capable of producing during the course of our life. We delve into the secrets of sleep, an action that will take up a third of our lives. We unravel the mysteries of REM sleep, how our brain uses it to order our memories and how we will dream 112,521 dreams before we die, but we’ll remember almost none of them. Astonishingly, however old we get our body is on average no older than 1 5.9 years, because it’s constantly regenerating itself.

We applaud the 73 stomach linings we’ll produce, the 24 layers of skin we’ll shed, and the 16 and � pints of blood we’ll generate every year. But there’s one organ you don’t replace – your brain. Essential to managing everything in our body, we count the 100 trillion connections necessary to make it run, and bottle up the 23, 999 pints of cerebral spinal fluid we’ll make to keep it in working order. Finally we step back and marvel at our body’s lifetime achievement; the 444 million pints of blood our heart will pump the 563 million breaths we will take, the 7.5 million cubic feet of air we will breathe, the 23 tons of food we will eat and 127 US pints of tears we will produce during the 77 years and 9 and a half months we, on average, will live.

This episode explores the numbers in the life of our human body – from the age of ten to middle age. To start with, it takes us along two different paths, following the development of both girls and boys. We follow a girl’s journey through puberty, her 409 grams of new bone each year enabling her to grow by 9.8 inches throughout adolescence. We see the effects of 200 hormones that can alter our body and change our emotions – causing a teenage girl to cry four times as much as a boy with 64 cries in a year. We follow a boy after his testosterone levels have soared 50 times transforming him into a man. We look at the 30,000 hairs which will sprout from his face and at the 170 square yards he will shave up until the age of just 50. And if all that is just too serious – there is always laughter. It’s the best workout of all. It uses 312 of our muscles. It takes up a lot of our energy – 228,125 calories by the age of 50 – enough to make over 1000 custard pies.

This episode follows the evolving journey of our lives, from one year old until the age of ten. We examine the numbers that lie behind our body’s development – our 640 controllable muscles and our 206 self repairing bones, stronger than concrete, but allowing us to be the most dexterous creatures on earth. We examine how we learn to walk; how we speak, read and write; how we can hear all 600 consonants and 200 vowels from the 6000 odd languages spoken across the world; and how by five we have a vocabulary of 2000 words. As we grow up into toddlers we look at our senses, examining the thousands of flavours and the 10,000 odours that we can detect; how our ears pick out 1,500 levels of sound. We explore our developing brain. At the age of three our brain has more connections than an adult’s – that’s 15,000 phone lines for each of the 100 billion of our brains nerve cells – all able to receive information from our 45 mile long nervous system.

From London to Los Angeles, Melbourne to Mecca, Buenos Aires to Bangkok we all have one thing in common – our body. We tend to take it for granted, blissfully unaware of the thousands of breaths we take each day, the millions of receptors our eyes use to see, or the billions of beats our heart will make in our life. In Body In Numbers we look at what an amazing creation your body is. We decode your body’s vital statistics in a way that will completely change the way you think about yourself. Can you imagine how much sweat you’ll produce in a lifetime or how many years you will spend asleep?

In Body In Numbers we will show you exactly what these statistics mean, pouring out all the tears you produce, the volume of blood you heart pumps in a day and laying out the number of light receptors in your eyes. In the first episode we examine the miracle of conception, how sperm has to swim the equivalent of six times across the Atlantic to reach the female egg, how that one fertilized cell will generate trillions of others, and how the information in your DNA would take nine and a half years to read out loud.
